The Efficacy of Topical Tranexamic Acid in Femoral Neck Fractured Patients Undergoing Cemented Bipolar Hemiarthroplasty: A Randomized Double Blinded Controlled Trial / A eficácia do ácido tranexâmico tópico em pacientes com fraturas no pescoço femoral submetidos a hemiartroplastia bipolar cimentada: Um ensaio controlado duplo-cego randomizado

Abstract Objective Tranexamic acid (TXA) is an antifibrinolytic that is widely used for decreasing blood loss and blood transfusion rates in total hip arthroplasty. However, there is limited evidence of topical TXA usage in hip hemiarthroplasty for femoral neck fractures. The present study aimed to evaluate the effects of topical TXA on blood loss and on blood transfusions in femoral neck fracture patients who underwent cemented bipolar hemiarthroplasty. Methods Twenty-six patients with femoral neck fractures who were scheduled for bipolar cemented arthroplasty were randomized into two groups. The first group of 12 patients received topical TXA during their operation, whereas 14 patients in the second group received a placebo. Hematocrit was measured at 6 and 24 hours postoperatively. Blood transfusions and postoperative complications were also recorded. Results Total blood loss was not different between the TXA group and the control group (TXA group: 459.48 ± 456.32 ml, and control group: 732.98 ± 474.02 ml; p = 0.14). However, there were no patients within the TXA group who required a blood transfusion, while there were 4 patients in the control group who received allogenic blood transfusions (p = 0.044). There were no postoperative complications, such as wound complication, venous thromboembolism, or cardiovascular complications within either group. Conclusion Topical TXA could not decrease total blood loss but was able to reduce transfusion rates in patients who underwent cemented bipolar hip hemiarthroplasty in femoral neck fractures. Further studies in doses of topical TXA in a larger sample size would be beneficial. Level of Evidence II.

Resumo Objetivo O ácido tranexâmico (TXA) é um antifibrinolítico amplamente utilizado para diminuir as taxas de perda de sangue e de transfusão de sangue na artroplastia total do quadril. No entanto, há evidências limitadas de uso tópico de TXA na hemiartroplastia do quadril para fraturas no pescoço femoral. O presente estudo teve como objetivo avaliar os efeitos do TXA tópico na perda de sangue e transfusões de sangue em pacientes com fratura femoral que foram submetidos a hemiartroplastia bipolar cimentada. Métodos Vinte e seis pacientes com fraturas no pescoço femoral e programados para artroplastia cimentada bipolar foram randomizados em dois grupos. O primeiro grupo de 12 pacientes recebeu TXA tópico durante a operação; no segundo grupo, 14 pacientes receberam placebo. O hematócrito foi medido às 6 e 24 horas no pósoperatório. Também foram registradas transfusões de sangue e complicações pósoperatórias. Resultados A perda total de sangue não foi diferente entre o grupo TXA e o grupo controle (grupo TXA: 459,48 ±456,32 ml; e grupo controle: 732,98 ±474,02 ml; p = 0,14). No entanto, não houve pacientes dentro do grupo TXA que necessitaram de transfusão de sangue, enquanto 4 pacientes no grupo controle fizeram transfusões de sangue halogênicas (p = 0,044). Não houve complicações pós-operatórias, tais como complicação da ferida, tromboembolismo venoso ou complicações cardiovasculares dentro de qualquer grupo. Conclusão O TXA tópico não conseguiu diminuir a perda total de sangue, mas foi capaz de reduzir as taxas de transfusão, em pacientes submetidos a hemiartroplastia de quadril bipolar cimentada em fraturas no pescoço femoral. Outros estudos com doses de TXA tópico em um tamanho amostral maior seriam benéficos. Nível de Evidência II.

Cemented Calcar Replacement versus Long Stem Cemented Hemiarthroplasty in Unstable Intertrochanteric Fractures in Octogenarians / Substituição do calcar cimentado versus hemiartroplastia de haste longa cimentada em fraturas intertrocantéricas instáveis em octogenários

Abstract Objective The aim of the present study was to compare functional results after Cemented Calcar replacement vis-a-vis Long stem Cemented hemiarthroplasty in patients aged more than 80 years with unstable intertrochanteric fractures. Methods The present prospective, randomized trial included 140 patients with AO/OTA type 31-A2, A3 intertrochanteric femur fracture, randomized into 2 treatment groups and followed-up for a minimum of 2 years. Sixty-seven patients in group A were treated with a cemented calcar replacing prosthesis, and 65 patients in group B were treated with a cemented long stem femoral stem prosthesis. The primary end points were hip functions at 2 years. The secondary end points were the complications encountered, mortality, surgical time, reoperation, blood loss, and activities of daily living. Results There were no major differences between the groups in terms of hip function, quality of life (health related), reoperation, mortality, and blood loss. However, the function in hip joint and activities of daily living deteriorated in both groups in comparison with prefracture levels. Conclusion In octogenarians with an unstable intertrochanteric fracture, cemented calcar replacing prosthesis has similar clinical results in comparison with long stem cemented hemiarthroplasty. Hemiarthroplasty with either implant is a good option in this subset of patients. Level of evidence: I

Resumo Objetivo O objetivo do presente estudo foi comparar os resultados funcionais após a substituição do Calcar cimentado em comparação com a hemiartroplastia cimentada de haste longa em pacientes com mais de 80 anos com fratura intertrocantérica instável. Métodos O presente estudo prospectivo e randomizado incluiu 140 pacientes com fratura de fêmur intertrocantérica, conforme classificação AO/OTA tipo 31-A2, A3, randomizados em 2 grupos de tratamento e acompanhados por um período mínimo de 2 anos. Sessenta e sete pacientes do grupo A foram tratados com uma prótese de substituição do calcar cimentada e 65 pacientes do grupo B foram tratados com uma prótese femoral de haste longa cimentada. Os desfechos primários foram as funções do quadril em 2 anos. Os eventos secundários foram as complicações encontradas, a mortalidade, o tempo cirúrgico, segunda cirurgia, perda de sangue e as atividades do cotidiano. Resultados Não houve grandes diferenças entre os grupos em termos de função do quadril, qualidade de vida (relacionada à saúde), segunda cirurgia, mortalidade e perda de sangue. No entanto, a função da articulação do quadril e as atividades da vida diária se deterioraram em ambos os grupos em comparação com os níveis pré-fratura. Conclusão Nos octogenários com fratura intertrocantérica instável, a prótese de substituição do calcar cimentada apresentou resultados clínicos semelhantes em comparação com a hemiartroplastia de haste longa cimentada. A hemiartroplastia comqualquer umdos implantes é uma boa opção nesse subgrupo de pacientes. Nível de evidência: I

[Interposition hemiarthroplasty using extensor hallucis brevis for the treatment of hallux rigidus with lateral unicompartmental involvement: a case report]. / Hemiartroplastía por interposición utilizando el extensor hallucis brevis para el tratamiento de hallux rigidus con involucro unicompartimental lateral: reporte de un caso.

Hallux rigidus is the degenerative pathology of the metatarsophalangeal joint of the hallux. This pathology causes pain and decreased movement. There are multiple surgical treatments for this pathology, all with their respective indications. We present the case of a 54-year-old patient diagnosed with hallux rigidus who had only the lateral aspect of the metatarsal head affected. This patient was treated with a novel surgical procedure, performing an interposition hemiarthroplasty using the hallucis brevis extender associated with a cheilectomy and exostectomy. The patient had a favorable clinical evolution with improvement evidenced by clinical scales, with resolution of the symptoms and without complications. Interposition hemiarthroplasty using the extensor hallucis brevis is a successful joint and movement preservation treatment for hallux rigidus in young patients with lateral unicompartmental involvement of the metatarsal head, in whom it is important to preserve movement.

El paciente tuvo una favorable evolución clínica con mejoría evidenciado por escalas clínicas, con resolución de la sintomatología y sin complicaciones. La hemiartroplastía de interposición utilizando el extensor hallucis brevis es un tratamiento exitoso de preservación articular y del movimiento para el hallux rigidus en pacientes jóvenes en los que hay afectación unicompartimental lateral de la cabeza metatarsiana, en quienes es importante preservar el movimiento.

[Functional results after shoulder hemiarthroplasty for proximal humerus fracture: experience in our center]. / Resultados funcionales tras hemiartroplastía de hombro por fractura de húmero proximal: experiencia en nuestro centro.

INTRODUCTION: shoulder hemiarthroplasty is being relegated as a treatment for non-osteosynthetic proximal humerus fractures. Our objective is to analyze the functional results of patients treated with hemiarthroplasty for this reason in our hospital. MATERIAL AND METHODS: cross-sectional descriptive study that includes patients operated between February 2016 and November 2021; 24 patients, with an average follow-up of 44.6 months. Active joint balance, the Constant-Murley test, the DASH questionnaire and current pain (VAS) were collected. The radiographic parameters analyzed were the number of fracture fragments and the consolidation of the tuberosities. RESULTS: a mean of 71.65 ± 13.75 was obtained in the Constant-Murley and 18.14% ± 13.92 in the DASH. For shoulder flexion, the mean was 108.75° ± 41.26; 104.5° ± 43.68 for abduction and 33° ± 14.73 for external rotation. About internal rotation, 60% of the patients reached the scapular plane. Average VAS was 1.25 ± 1.74. Consolidated tuberosities in 90.5%. There were no significant differences comparing the Constant-Murley test, DASH or rotations between both, over and under 65 years old group of patients. Those over 65 years of age obtained a mean flexion of 125.91° ± 26.82 whereas those under 87.78° ± 26.82 (p = 0.038). The mean abduction in those over 65 was 125.45 ± 28.94 vs 78.89 ± 46.29 in the young group (p = 0.012). CONCLUSION: hemiarthroplasty provides quality of life with acceptable functionality and good pain control, therefore it should continue to be an alternative to consider in selected patients.

Total hip arthroplasty versus hemiarthroplasty for displaced femoral neck fracture: a protocol for an overview of systematic reviews.

INTRODUCTION: Hip arthroplasties for the treatment of displaced femoral neck fractures in adults can be total replacement or hemiarthroplasty. Despite the high prevalence of these fractures and large number of studies on the topic, the best choice of arthroplasty to be used remains unclear. The present study aims to overview the results of systematic reviews of randomised controlled trials (RCTs) comparing outcomes between total hip replacement and hemiarthroplasty for displaced femoral neck fractures in adults. METHODS AND ANALYSIS: Four electronic databases (Pubmed, Embase, Cochrane Library and Web of Science) and reference lists from previous reviews will be searched without language limitation. Eligible studies will be systematic reviews of RCT that compare total hip replacement and hemiarthroplasty for treatment of displaced femoral neck fractures in adults. Two reviewers will independently perform study selection, data extraction and quality assessment. Disagreements between reviewers will be resolved by a third reviewer. Comparisons of dichotomous data will report as the OR and 95% CI, and comparisons of functional and health-related quality of life outcomes are reported as the mean difference and 95% CI and as the risk difference, defined as the difference in the proportion achieving the minimum clinically important difference and 95% CI. As this overview will contribute to orthopaedic surgeons and health managers in better decision-making for the treatment of these fractures. The authors plan to complete the searches and analyses by 30 November 2021. ETHICS AND DISSEMINATION: Ethical approval was obtained at Federal University of Sao Paulo. Findings will be disseminated through peer-reviewed publication. PROSPERO REGISTRATION NUMBER: CRD42021237885.

[Results of the treatment of primary glenohumeral osteoarthritis through hemiarthroplasty]. / Resultados del tratamiento de la artrosis glenohumeral primaria mediante hemiartroplastía.

INTRODUCTION: Glenohumeral osteoarthritis leads to a functional loss and a decrease in the quality of life of many patients that suffers it. Currently there is no agreement on the use of hemiarthroplasty or total arthroplasty as definitive treatment. The objective is to show the results of the treatment of primary glenohumeral osteoarthritis through hemiarthroplasty in our service. MATERIAL AND METHODS: We reviewed 14 patients (19 hemiarthroplasties) performed between 2004 and 2013 in patients diagnosed with primary glenohumeral osteoarthritis without glenoid morphological anomaly. We managed to collect data from eight patients (11 hemiarthroplasties), assessing functional status, pain, and performing activities of daily living using the Constant, ASES and DASH scores preoperatively and at five years of minimum follow-up (range 5-11 years), as well as related complications. The preoperative status was compared to the end of the follow-up. RESULTS: A significant improvement was found in all the parameters analyzed in the study (p. CONCLUSION: < 0.05). The average pain in EVA score decreased from 8.89 to 2.67. The ASES improved from 13.51 to 63. 51 half point. The Constant increase of 20.11 points to 65.11 points. The mean preoperative score in the DASH score was 73.68 and 28.30 postoperatively. The average survival of the implant was 81.82% in the seven years of average follow-up. Shoulder hemiarthroplasty obtains good functional results in the treatment of primary glenohumeral osteoarthritis with few complications. The cause of the failure were glenoid erosion in all the cases.

Prolonged social lockdown during COVID-19 pandemic and hip fracture epidemiology.

PURPOSE: To analyse the impact of prolonged mandatory lockdown due to COVID-19 on hip fracture epidemiology. METHODS: Retrospective case-control study of 160 hip fractures operated upon between December 2019 and May 2020. Based on the date of declaration of national lockdown, the cohort was separated into two groups: 'pre-COVID time' (PCT), including 86 patients, and 'COVID time' (CT), consisting of 74 patients. All CT patients tested negative for SARS-CoV-2. Patients were stratified based on demographic characteristics. Outcome measures were 30-day complications, readmissions and mortality. A logistic regression model was run to evaluate factors associated with mortality. RESULTS: Age, female/male ratio, body mass index and American Society of Anaesthesia score were similar between both groups (p > 0.05). CT patients had a higher percentage of Charlson ≥ 5 and Rockwood Frailty Index ≥ 5 scores (p < 0.05) as well as lower UCLA and Instrumental Activities of Daily Living scores (p < 0.05). This translated into a higher hemiarthroplasty/total hip arthroplasty ratio during CT (p = 0.04). Thromboembolic disease was higher during CT (p = 0.02). Readmissions (all negative for SARS-CoV-2) were similar between both groups (p = 0.34). Eight (10.8%) casualties were detected in the CT group, whereas no deaths were seen in the control group. Logistic regression showed that frailer (p = 0.006, OR 10.46, 95%CI 8.95-16.1), less active (p = 0.018, OR 2.45, 95%CI 1.45-2.72) and those with a thromboembolic event (p = 0.005, OR 30, 95%CI 11-42) had a higher risk of mortality. CONCLUSION: Despite testing negative for SARS-CoV-2, CT patients were less active and frailer than PCT patients, depicting an epidemiological shift that was associated with higher mortality rate.

[Incidence of epidural spread after Chayen's approach to lumbar plexus block: a retrospective study]. / Incidência de dispersão peridural após bloqueio do plexo lumbar com técnica de Chayen: estudo retrospectivo.

BACKGROUND AND OBJECTIVES: The lumbar plexus block (LPB) is a key technique for lower limb surgery. All approaches to the LPB involve a number of complications. We hypothesized that Chayen's approach, which involves a more caudal and more lateral needle entry point than the major techniques described in the literature, would be associated with a lower rate of epidural spread. METHOD: We reviewed the electronic medical records and chart of all adult patients who underwent orthopedic surgery for total hip arthroplasty (THA) and hip hemiarthroplasty due to osteoarthritis and femoral neck fracture with LPB and sciatic nerve block (SNB) between January 1, 2002, and December 31, 2017, in our institute. The LPB was performed according to Chayen's technique using a mixture of mepivacaine and levobupivacaine (total volume, 25 mL) and a SNB by the parasacral approach. The sensory and motor block was evaluated bilaterally during intraoperative and postoperative period. RESULTS: A total number of 700 patients with American Society of Anesthesiologists (ASA) physical status I to IV who underwent LPB met the inclusion criteria. The LPB and SNB was successfully performed in all patients. Epidural spread was reported in a single patient (0.14%; p <0.05), accounting for an 8.30% reduction compared with the other approaches described in the literature. No other complications were recorded. CONCLUSIONS: This retrospective study indicates that more caudal and more lateral approach to the LPB, such as the Chayen's approach, is characterized by a lower epidural spread than the other approach to the LPB.

Resumo Justificativa e objetivos: O bloqueio do plexo lombar (BPL) é uma técnica fundamental para a cirurgia de membros inferiores. Todas as abordagens do BPL são associadas a uma série de complicações. Nossa hipótese foi de que a abordagem de Chayen, que envolve um ponto de entrada da agulha mais caudal e mais lateral do que as principais técnicas descritas na literatura, estaria associada a menor incidência de dispersão peridural. Método: Revisamos os prontuários médicos eletrônicos e em papel de todos os pacientes adultos submetidos à artroplastia total do quadril (ATQ) e hemiartroplastia do quadril devido a osteoartrite ou fratura do colo do fêmur empregando-se BPL associado ao bloqueio do nervo ciático (BNC), entre 1 de janeiro de 2002 e 31 de dezembro de 2017 em nossa instituição. Realizamos o BPL usando a técnica de Chayen e uma mistura de mepivacaína e levobupivacaína (volume total de 25 mL) e o BNC pela abordagem parassacral. Testes sensorial e motor bilaterais foram realizados no intra e pós-operatório. Resultados: Os critérios de inclusão foram obedecidos pelo total de 700 pacientes classe ASA I a IV submetidos ao BPL. Os BPL e BNC foram realizados com sucesso em todos os pacientes. A dispersão peridural foi relatada em um único paciente (0,14%; p < 0,05), representando uma redução de 8,30% quando comparada às outras abordagens descritas na literatura. Nenhuma outra complicação foi registrada. Conclusões: Este estudo retrospectivo indica que a abordagem mais caudal e mais lateral do BPL, como a técnica de Chayen, é caracterizada por menor dispersão peridural do que outras abordagens do BPL.

Background The bone cement implantation syndrome (BCIS) is a frequent and potentially devastating intraoperative complication in patients undergoing cemented hip arthroplasty. The objective of study is to describe the frequency of BCIS in patients undergoing total or partial hip arthroplasty. Methods Case series study. We reviewed the medical records of adult patients over 50 years of age with an indication for Arthroplasty or Hemiatroplasty. The perioperative variables were analyzed through the Anesthesia registry. The degree of SICO was determined by Donaldson classification. Descriptive statistics and multiple correspondence analysis were used to explore the relationship between the variables. Results We included 49 patients with an average age of 78 years (SD +/- 9.9), 39 were women (79.6%) and 37 (75.5%) had an ASA II classification. We documented the presence of SICO in 8 patients (16.3%): of which 5 corresponded to Grade 1, 2 Grade 2 and 1 to Grade 3 with ICU requirement. 7 were women; all were hypertensive, 2 diabetes mellitus, 2 COPD and 1 osteoporosis. None reported Warfarin ingestion. Discussion BCIS is a frequent phenomenon in the arthroplasty and cemented hemiarthroplasty, being higher in the female sex, documenting the presence of predictors of severity ASA II -III classification and the history of COPD in our hospital.

APSI scaphoid hemiarthroplasty - long-term results / Hemiartroplastia do escafoide com APSI - resultados funcionais em longo prazo

ABSTRACT Objective: This study is aimed at evaluating the long-term results of proximal scaphoid hemiarthroplasty for post-traumatic avascular necrosis at this institution. Methods: Twelve patients who underwent this procedure were identified, and the mean follow-up time was 6.5 years (range: 5-8 years). All patients were male, with a mean age of 39 years (range: 28-55 years). In eight patients, the non-dominant limb was affected. The procedure was carried out through a dorsal approach and all patients underwent the same rehabilitation protocol. Cases were evaluated regarding complications, pain, range of motion, functional status (Mayo Wrist Score), and disability (QuickDASH Score). Results: No immediate post-operative complications, such as infection or dislocation of the implant, were observed. All patients presented with peri-implant osteolysis at follow-up, on a radiograph study. None of the patients was forced to abandon their previous professional activity, although about 50% required some type of adaptation at their workplace. The mean functional capacity was, according to the Mayo Wrist Score, of 67.5 points (range: 50-80), corresponding to a satisfactory degree of function. The QuickDASH disability score presented a mean of 25 (range: 3-47.7). Conclusion: The results of this series are in line with previously published studies about this technique. Hemiarthroplasty with a pyrocarbon implant is a safe technique for the treatment of post-fracture avascular necrosis of the scaphoid proximal pole. This technique allowed for satisfactory functional results at a mean follow-up of 6.5 years.

RESUMO Objetivo: Avaliar os resultados em longo prazo da hemiartroplastia do escafoide proximal no tratamento da osteonecrose avascular pós-traumática na instituição. Métodos: Foram identificados 12 pacientes submetidos a esse procedimento. O tempo médio de seguimento foi de 6,5 anos (entre cinco e oito). Todos os pacientes eram do sexo masculino, com média de 39 anos (entre 28 e 55). Em oito pacientes o membro afetado foi o não dominante. O procedimento foi feito por meio de uma abordagem dorsal e todos os pacientes foram submetidos ao mesmo protocolo de reabilitação. Todos os casos foram avaliados quanto à ocorrência de complicações, dor, amplitude de movimento, capacidade funcional (Mayo Wrist Score) e incapacidade (QuickDASH Score). Resultados: Não foram observadas complicações no período pós-operatório imediato, como infeção ou luxação do implante. No fim do período de seguimento, todos os casos apresentavam osteólise peri-implante no estudo radiográfico. Nenhum dos pacientes abandonou a sua atividade profissional prévia à cirurgia, embora em cerca de 50% dos casos tenha sido necessário algum tipo de adaptação no local de trabalho. A capacidade funcional média foi, de acordo com o Mayo Wrist Score, de 67,5 pontos (entre 50 e 80), correspondeu a um nível de função satisfatório. O escore de incapacidade QuickDASH apresentou uma pontuação média de 25 (entre 3 e 47,7). Conclusão: Os resultados desta série encontram-se em linha com os estudos publicados sobre essa técnica. A hemiartroplastia do escafoide com implante de pirocarbono é uma técnica segura para o tratamento da necrose avascular do polo proximal do escafoide após fratura. Essa técnica permitiu obter um resultado funcional satisfatório após uma média de 6,5 anos de seguimento.

Trends in surgical treatment of femoral neck fractures in the elderly.

OBJECTIVE: To analyze recent demographic and medical billing trends in treatment of femoral neck fracture of American elderly patients. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was analyzed from 2006 to 2015, for patients aged 65 years and older, using the Current Procedural Terminology codes 27130, 27125, 27235, and 27236. Patient demographics, postoperative complications, and frequency of codes were compared and analyzed over time. Our sample had 17,122 elderly patients, in that, 70% were female, mean age of 80.1 years (standard deviation±6.6 years). RESULTS: The number of cases increased, but age, gender, body mass index, rates of diabetes and smoking did not change over time. Open reduction internal fixation was the most commonly billed code, with 9,169 patients (53.6%), followed by hemiarthroplasty with 5,861 (34.2%) patients. Combined estimated probability of morbidity was 9.8% (standard deviation±5.2%), and did not change significantly over time. Postoperative complication rates were similar between treatments. CONCLUSION: Demographics and morbidity rates in femoral neck fractures of elderly patients did not change significantly from 2006 to 2015. Open reduction internal fixation was the most common treatment followed by hemiarthroplasty.

Intrathoracic fracture-dislocation of the humerus - case report and literature review / Fratura luxação intratorácica do úmero - Relato de caso e revisão da literatura

ABSTRACT Shoulder fracture-dislocations are uncommon. Those associated with intrathoracic dislocation are very rare conditions, resulting from high-energy trauma; usually, the affected limb is in an abduction position. In Brazil, there is only one report of a teenager with displacement of the epiphysis into the chest cavity; the present is the first adult patient report of intrathoracic dislocation of the humerus. The authors present the case of a patient female, aged 56 years, who was hit by motorcycle and thrown approximately 5 meters away. She was rescued on site with thoracic, pelvic, and right upper limb trauma. Her chest was drained due to pneumothorax and multiple fractures of ribs; she was diagnosed with fracture-dislocation in four parts, with intrathoracic dislocation of the humeral head. Displaced forearm bones fracture was also diagnosed; the olecranon, scaphoid, and ischiopubic fractures were not displaced. The patient underwent a joint procedure with a cardiothoracic surgery team to remove the humeral head through thoracotomy and chest drainage; subsequently, a partial arthroplasty of the humerus was performed, with graft from the humeral head and fixation of forearm fractures. Conservative treatment was chosen for the other fractures. After three months, all fractures were healed with gradual functional improvement. The patient remained in physiotherapy and orthopedic monitoring, having been discharged from the thoracic surgery; in a severe depressive episode, the patient committed suicide after 11 months of the trauma.

RESUMO As fraturas luxações do ombro são incomuns; aquelas associadas com deslocamento intratorácico são condições muito raras e decorrentes de traumas de alta energia, nos quais o membro acometido geralmente está numa posição de abdução. No Brasil, existe apenas o relato de um adolescente com deslocamento da epífise para o interior da caixa torácica. Esse é o primeiro relato de paciente adulto com luxação intratoracica de umero. Os autores apresentam um caso de paciente feminina de 56 anos, atropelada por motocicleta e arremessada em torno de cinco metros de distância. Foi socorrida no local com trauma torácico, pélvico e do membro superior direito. Teve o tórax drenado devido a pneumotórax e múltiplas fraturas de arcos costais e recebeu o diagnóstico de fratura luxação em quatro partes com deslocamento intratorácico da cabeça umeral. Foram diagnosticadas fratura de ossos do antebraço desviada e fraturas do olécrano, do escafoide e dos ramos isquiopúbicos sem desvios. A paciente foi submetida a procedimento cirúrgico conjunto com uma equipe de cirurgia cardiotorácica para retirada da cabeça umeral por meio de toracotomia e drenagem torácica; posteriormente, uma artroplastia parcial do úmero foi feita, com enxertia proveniente da cabeça umeral, além de fixação das fraturas do antebraço. Nas demais fraturas, optou-se por tratamento conservador. Após três meses, todas as fraturas apresentavam-se consolidadas com melhoria gradual das funções. A paciente permaneceu em acompanhamento fisioterápico e ortopédico e recebeu alta da cirurgia torácica. Dentro de um quadro depressivo grave, cometeu suicídio 11 meses após o trauma.
